[BUG]: Service-override works inconsistently with go-redis v9

[d33kayyy]

Tracer Version(s)

2.4.1

Go Version(s)

1.25

Bug Report

I have multiple Go projects with identical setups. However, the tracing is working correctly with one project but not the other, in which the service-override cannot identify the correct dependency for a project. As a result, the time spent by downstream services is also incorrect.

I don't know if I should post it here or elsewhere, please advice.

Reproduction Code

go.mod

	github.com/DataDog/dd-trace-go/contrib/gin-gonic/gin/v2 v2.2.3
	github.com/DataDog/dd-trace-go/contrib/go-redis/redis/v2 v2.2.3
	github.com/DataDog/dd-trace-go/contrib/redis/go-redis.v9/v2 v2.2.3
	github.com/DataDog/dd-trace-go/v2 v2.4.1
	github.com/DataDog/orchestrion v1.5.0

orchestrion.tool.go

// This file was created by `orchestrion pin`, and is used to ensure the
// `go.mod` file contains the necessary entries to ensure repeatable builds when
// using `orchestrion`. It is also used to set up which integrations are enabled.

//go:build tools

//go:generate go run github.com/DataDog/orchestrion pin -generate

package tools

// Imports in this file determine which tracer integrations are enabled in
// orchestrion. New integrations can be automatically discovered by running
// `orchestrion pin` again. You can also manually add new imports here to
// enable additional integrations. When doing so, you can run `orchestrion pin`
// to make sure manually added integrations are valid (i.e, the imported package
// includes a valid `orchestrion.yml` file).
import (
	// Ensures `orchestrion` is present in `go.mod` so that builds are repeatable.
	// Do not remove.
	_ "github.com/DataDog/orchestrion" // integration

	// Just import the necessary integrations
	_ "github.com/DataDog/dd-trace-go/contrib/gin-gonic/gin/v2"     // integration
	_ "github.com/DataDog/dd-trace-go/contrib/go-redis/redis/v2"    // integration
	_ "github.com/DataDog/dd-trace-go/contrib/redis/go-redis.v9/v2" // integration
	_ "github.com/DataDog/dd-trace-go/v2/contrib/os"                // integration
	_ "github.com/DataDog/dd-trace-go/v2/ddtrace/tracer"            // integration
	_ "github.com/DataDog/dd-trace-go/v2/orchestrion"               // integration
	_ "github.com/DataDog/dd-trace-go/v2/profiler"                  // integration
)

environment variables

  DD_TRACE_ENABLED: "true"
  DD_APPSEC_ENABLED: "false"
  DD_LOGS_INJECTION: "true"

Both apps are built from alpine public.ecr.aws/docker/library/golang:1.25-alpine with args

code that create the redis client

package cache

import (
	"fmt"

	"github.com/redis/go-redis/v9"

	"pkg/config"
)

func New(cfg *config.Config) (*redis.Client, error) {
	if cfg == nil {
		panic("config is required")
	}

	uri := cfg.Redis.URI
	if uri != "" {
		opt, err := redis.ParseURL(uri)
		if err != nil {
			return nil, err
		}
		return redis.NewClient(opt), nil
	}

	return redis.NewClient(&redis.Options{
		Addr:     fmt.Sprintf("%s:%d", cfg.Redis.Host, cfg.Redis.Port),
		Password: cfg.Redis.Password,
		DB:       cfg.Redis.DB,
	}), nil
}

Thanks @d33kayyy for the detailed repo. Allow me to ping @rarguelloF so his team can check this.

Hello @d33kayyy and thanks for reporting this issue.

If you want to get completely rid of the service overrides set from integrations, you can set the configuration: DD_TRACE_REMOVE_INTEGRATION_SERVICE_NAMES_ENABLED=true (see more info here).

Also, if you are still facing issues, I recommend you to contact the DataDog support so our team can assist you better by looking at your organization specific details.

Hi,

DD_TRACE_REMOVE_INTEGRATION_SERVICE_NAMES_ENABLED=true does not work, and neither false

Our temporary solution is to explicitly patch the redis client in some projects so that the metrics show correctly.

	redistrace "github.com/DataDog/dd-trace-go/contrib/redis/go-redis.v9/v2"
...
	redistrace.WrapClient(client, redistrace.WithService("redis"))
